You will have something like this : 7V745xxxxxx the 45 means it was produced on the 45th week. iPhones from week 45 and above have the new boot loader version 4.6 with the 1.1.2 Firmware which is unlockable without a TurboSim. Continue reading the entire guide below:You can also check the Modem Firmware version of your iPhone by doing the following.

1- Turn on your iPhone, you will get “Slide for Emergency Call”
2- Slide and you will get the phone keypad

If you have the version 04.02.12_G you are sure to have the boot loader version 4.6 which in unlockable without a TurboSim.

What you can do now is downgrade your firmware 1.1.2 to a firmware 1.1.1, by doing that you can use every aspect of your iPhone except all the functions that need a SIM card.

Key Terms to know:DOWNGRADE: go from firmware 1.1.2 to firmware 1.1.1 ACTIVATE: Bypass the AT&T activation to have access to all the functions in the iPhone JAILBREAK: gives you the ability to install 3rd party applications on the iPhone.

At this step if you don’t have iTunes installed on your Computer please visit the apple website and download and install iTunes.

– Next Plug your USB in your computer and in your iPhone, iTunes will automatically open and give you an ACTIVATION page.

-Now press the MENU BUTTON and THE POWER BUTTON at the same time and keep pressing them until iTunes tells you that it has detected that your iPhone is in recovery Mode, this could take something from 10 seconds to 30 seconds, so keep pressing both buttons until you get the message.

– Once you get the message dismiss the warning message in iTunes (iTunes has detected …..) by pressing OK and now you have 2 options , the first is Search for Updates and the second, that we will use is RESTORE.

BEFORE YOU PRESS ON THE RESTORE BUTTON YOU NEED TO PRESS YOUR SHIFT BUTTON IN WINDOWS (OPTIONS BUTTON IN MAC) AND THEN PRESS RECOVER.

Now a “Browse your files” window will open, go and chose the firmware 1.1.1 file you have downloaded in step 1 and press open.

iTunes will start downgrading your iPhone (this takes some time) and the downgrade process will end up with an error message 1013 or 1015 THIS IS VERY NORMAL

-Next if you are using Windows Open iBrickr and chose the Option “Reboot my iPhone” to kick your iPhone out of the Recovery Mode

Now you iPhone will restart and you will have an ACTIVATION PAGE on your iPhone with the nice round World image.

STEP3 – Activate And Jailbreak

Before you complete this part MAKE SURE that the AT&T Sim card is in your phone

Now, you are on the activation screen that says slide to make an emergency call, slide to get to the keypad and then do the following:

Dial *#307# and hit call

The iPhone will now start to ring itself, once it start to ring you have to erase *#307# by using the backslash button on your iPhone and then type 0 and then CALL, the iPhone will ring again and this time hit “Answer” then hit “Hold”, the Phone will start to ring itself again, this time click “Decline”.

Now on the screen you should be able to get to the contacts menu down the bottom, tap “Contacts” and then add a contact. Use the following instructions:

Add the Name “Testing” and tap save
Tap “Add URL” and type “prefs://1F” then tap save
Tap “Add URL” again and type “http://jailbreakme.com” then tap save

When this is done, tap “Save” again and it will take you to the contact page displaying the name “Test” and the two URLs you just added. Tap the “prefs://1F” URL and it will open the iPhone Settings page.

Tap “General” and Then “Auto-Lock”, set it to “Never”.

Go back to the settings page

From here, tap WiFi and Add your WiFi network and make sure you are connected to it

Now, hit the Menu button to go back to the Activation Screen, slide and dial the number 0, the iPhone will now ring itself again, tap answer, then hold, then decline just like before.

Now, hit contacts again and then Testing, this time go to the “jailbreakme.com” URL
Safari will open and loan the page, PRESS ON THE TOP OF THE SCREEN TO GET THE ADDRESS BAR AND CHANGE IT TO “http://jailbreakme.com” and hit GO when the page loads scroll to the bottom and click on “Install AppSnapp”.

Safari will now close and your iPhone will now go back to the Activation Screen.

Once you get to the activation screen slide to get to the dial pad again and when you do this iPhone will restart by itself and thats it, your now Activated and jail broken.

STEP4 – Upgrade To Firmware 1.1.2 & Activate And Jailbreak

-Click on INSTALLER on your iPhone (Blue Icon usually the last one)
If you are asked to update your Installer please do it (if you updated don’t forget after the update installs press the HOME button, it will take you back to the SLIDE TO UNLOCK page )

-Now open your iTunes on your PC or MAC and press on the name of your iPhone in the left column, this will take you to the page with UPDATE or RESTORE buttons.

On your iPhone click on INSTALLER and press on TWEAKS 1.1.1 and press and install Oktoprep, once it is installed it will give you a message on your iPhone saying “YOUR PHONE IS NOW READY TO BE UPGRADED TO 1.1.2 ……..” press OK and then press the HOME button and it will take you back to the SLIDE TO UNLOCK.

-Your iTunes is still open on your PC or MAC now press UPDATE and iTunes will update your iPhone to FIRMWARE 1.1.2 and this time you will not get an error message like the last time when you downgraded to 1.1.1. When the Update is finished you will get a picture of a plug that will appear on your iPhone and you will have the page SLIDE TO UNLOCK but written in French

Im currently running on a jailbreaked and unlocked 1.1.2 iphone and everything seemed to be working fine until this week i noticed that i cant install or do updates from installer… When i want to install a package it crashes at the “installing package” process.
